Ecology of Etmopterus lucifer
 
Main Ref. Compagno, L.J.V., 1984
Remarks Found on the outer continental and insular shelves and upper slopes (Ref. 247, 75154). Benthopelagic at 183-823 m (Ref. 58302). Its luminescent belly may attract prey (Ref. 26346), which consists mainly of squid (reported to bite squid bigger than itself), small bony fishes, and shrimps (Ref. 247). Often caught in large schools which may suggest that the luminescence may also be used to keep the group together in the dark deep ocean (Ref. 26346). Feeds om myctophids and cephalopods (Ref. 58748).
